I'm in the process of determining this,I've also used 4 differant mailing components all having the same effect, clearly the issue is with exchange, not the mailing components.

Actually no - it is a sense of sensless settings. Email is NOT a file sharing protocol. I have blocks on 8mb in place.

We try to block out anything that is an executable, and if I'm configuring a mail server try to keep the limits to less than 10 meg. If I'm in a more draconian mood 5. Anything else, set it up on a web server or direct transfer over skype or instant messaging. But that's me.

what configuration values specifically can cause this issue on exchange? What are the values I need to check for?
